Application filed April 7, 1906.

To all who m: it may concern:

Be it known that I, EDWARD G. Bonn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cushions, (Case C1,) of which the following is a specification.

This invention concerns cushions and refers particularly to cushions for use as.

hacks for seats of the ployed in cars.

The object of the invention is to so improve the construction of seat-back cushions as to increase the strength thereof and to make them more comfortable foroceupants of the seat. 1

In order that the seat shall possess ample strength I employ a frame of metal, this being formed of sheet-metal parts pressed to the desired shape and therefore being comparatively inexpensive.

type commonly ein- This frame is so constructed as to give to the compieted cushion a shape most conducive to the coinfort of the occupants of the seat, this being of the cushion material as to and above it a end-form pieces at the ends which so shape the covering form a. curved body portion curved head-roll. The usual slats are employed extending across the frame and se cured at their ends thereto, and in order to prevent the cushion covering from drawing the end-form pieces inwardly I employ braces secured thereto and to one or more of the transverse slats.

I have illustrated the preferred embodiment of my invention in the accompanying drawings, in which Figure 1 isa front view of a seat-back cushion, Fig. 2 is an end view of the same, Fig. I? is a top and Fig. 4 is a section on line 44 of Fig. 1.

Referring to these drawings, the frame of the cushion is of rectangular shape and is formed of metallic frame-sections secured together at their ends; the frame may consist of four such sections, but since in seatback cushions it is desirable to have the upper corners'rounded off, I prefer to make the frame from two sections, one, indicated by the numeral Leonstituting the bottom of the frame and the other, 2, bent to form the to frame sections may vary to suit conditions view of the end of the frame,

but is preferably that illustrated in Fig. 4, 111 Which the frame section 2 is shown as consisting of a body portion 3 and flanges 4' and 5 at the sides thereof, the extreme edges of these flanges being curled to -provide a smooth edge and to facilitate attaching the covering material thereto. The frame sections are secured together in any suitable manner, as by providing overlapping por tions on the flanges and a collar lying between these overlapping flanges into the ends of which the material of the flanges may be sunk. Extending across the frame and secured at their ends to the top and bottom thereof are a plurality of channeled transverse rails or slats 6 which support the usual spiral springs over which the covering is drawn.

At each end of the cushion is an end-formpiece 7, which gives shape to the'eovering of the cushion. This piece is formed of a strip of metal of uniform and substantially U shaped cross-section, as shown in Fig. 4. The greater portion of the length of this strip is bent in the direction of its length to the are of a circle and the lesser portion is also curved in a similar manner, the connection between the two ares being a smooth rounding one. The shape of the end-form iece is best shown in Fig. 2, in which it WiIl be seen that it has a large curved portion for the body of the cushion and a small curved portionfor the head-roll. Each of the two end-formpieees is escured upon one of the end -members ofthe frame with the bottom of the U outwards by rivets 8 at the ends of the piece and at the junction of the body and roll portions. ed as shown rounded upper corners, the upper en pieces 7 are curved laterally as shown in Figs. 1 and 3 to conform to the shape of the rounded corners and may be'eut away somewhat on the inside of this curve, as indicated at 9 (Fig. l) to facilitate securing its upper end to the frame. In order to stiffen the construetion and hold the pieces 7 against being pulled laterally by the covering, I provide angw lar braces 10 arranged to transmit a portion of the strain on the end-form ideas to one or more of the slats ,6. These fiaces may be sheet-metal strips flanged at the edges' to give them greater strength and'havingfeet at the ends perforated to receive rivets. One end of each of these braces is secured to the end slat 6 and the other to the end-form sof the headin. the drawings to rovide" 'the addition of the,

piece 7, the point of connection of the brace to the latter being near the top of the curve of the body portion. Of course, if desired 1 more than one brace may be used at each end of the cushion.

With the frame constructed in this manner, the spiral springs are secured upon the slats 6 and fiat springs .are supported on these spiral springs in the usual manner. T covering material is springs and the end-form pieces 7, its edges being drawn down tightly and secured to the frame. It 'will be seen that the pieces 7 give sha e to the covering and cause it to form a ho y ortion and a head-roll, the shape which as been'found to contribute most to the comfort of occupants of a seat. A frame constructed from metallic parts in the manner described possesses ample strength and braces 10 stifiens the where displacement structure at points would be a t to occur. The U-shaped crossseetional siiape of.the end-form pieces and mounting-themwith the bottom of the U outwards affords a wide support for the covering at the ends ofthe frame and one whic avoids the danger of the pieces cutting through the fabric along the edges of cushion.

Having now described my invention, what I claim as new therein and esire to secure by Letters Patent is as follows r 1.
